  • jQuery table filter with text, checkboxes, selects

    - by Jeffrey
    Need to filter a table from outside of the table, with a text search, checkboxes, and selects. PicNet Table Filter for jQuery works for both searching and using checkboxes outside of the table... though I can't find any examples of how to get a select box to work. Anyone know? *I might be getting too specific here, but thought I'd at least inquire. I'm also open to possibilities other than PicNet.

  • Android App Widget: Data storage

    - by Jeffrey
    Hello everyone, I'm implementing a home screen app widget. I was wondering which is better to store/read data: SharedPreferences or a SQLite database? The data is accessed from an AppWidgetProvider (similar to a BroadcastReceiver), and any given instance of the widget displays different data based on appWidgetId. Is one way or the other frowned upon? Thanks for your time.

  • Double-Escaped Unicode Javascript Issue

    - by Jeffrey Winter
    I am having a problem displaying a Javascript string with embedded Unicode character escape sequences (\uXXXX) where the initial "\" character is itself escaped as "&#92;" What do I need to do to transform the string so that it properly evaluates the escape sequences and produces output with the correct Unicode character? For example, I am dealing with input such as: "this is a &#92;u201ctest&#92;u201d"; attempting to decode the "&#92;" using a regex expression, e.g.: var out = text.replace('/&#92;/g','\'); results in the output text: "this is a \u201ctest\u201d"; that is, the Unicode escape sequences are displayed as actual escape sequences, not the double quote characters I would like.

  • 'Forward-Compatible' Program Design

    - by Jeffrey Kern
    The majority of my questions I've asked here so far on StackOverflow have been how to implement individual concepts and techniques towards developing a software-based NES clone via the XNA environment. The small samples that I've thrown together on my PC work relatively great and everything. Except I hit a brick wall. How do I merge all of these samples together. Having proof-of-concept is amazing, except when you need it to go beyond just that. I now have samples strewn about that I'm trying to merge, some of them incomplete. And now I'm stuck with the chicken-and-the-egg situation of where I would like to incorporate these samples together, to make sure they work, but I cannot without test data. And I don't have tools to create test data, because they'd need to be based off of the individual pieces that need to be put together. In my mind, I'm having nightmares with circular reference. For my sample data, I am hoping to save it in XML and write a specification - and then make sample data by hand - but I'm too paranoid of manually creating an XML file full of incorrect data and blaming it on my code, or vice-versa. It doesn't help that the end-result of my work is graphic-oriented, which makes it interseting how a graphic on the screen can be visualized in XML Nodes. I guess, my question is this: What design patterns and disciplines exist in the coding world that address this type of concern? I've always relied on brute-force coding and restarting a project with a whole new code base in attempts to further along my goals, but I doubt that would be the best way to do so. Within my college career, the majority of my programming was to work on simple projects that came out of a book, or with a given correct data set and a verifyable result. I don't have that, as my own design documents that I am going by could be terribly wrong.

  • Best practices retrieving XML/stream from HTTP in Android

    - by Jeffrey
    Hello everyone, what are the best practices parsing XML from an HTTP resource in Android? I've been using HttpURLConnection to retrieve an InputStream, wrapping it with a BufferedInputStream, and then using SAX to parse the buffered stream. For the most part it works, though I do receive error reports of SocketTimeoutException: The operation timed out or general parsing error. I believe it's due to the InputStream. Would using HttpClient instead of HttpURLConnection help? If yes, why? Should the stream be output to a file, having the file parsed instead of the stream? Any input or direction would be greatly appreciated. Thanks for your time.

  • Is it possible to broadcast audio to shoutcast / icecast / other server? from flash player?

    - by Jeffrey
    I am trying to create a flash client that can stream audio to an online radio server. Theoretically a user could enter the server info / login, and then connect and start sending data to the server which could then be broadcasted and listened to by other clients. I don't think this would be very hard, but am unsure about what data formats to use and what is the best server for the job. I'd like to be able to use one of the most popular radio servers like shoutCast. Any ideas? Thanks in advance.

  • JSF Templating without RAD

    - by Jeffrey Knight
    I have a set of jsp's based off a jtpl template. The template (jtpl file) looks like this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <%-- tpl:metadata --%> <%-- jsf:codeBehind language="java" location="/JavaSource/pagecode/my.java" --%> <%-- /jsf:codeBehind --%> <%-- /tpl:metadata --%> <%@taglib uri="http://www.ibm.com/jsf/html_extended" prefix="hx"%> <%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%> <HTML> <%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%> <%@page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <f:view> <HEAD> ... Without using RAD, how can I change the jtpl (template) and regenerate jsp? I'm looking for a command line solution. Related question: is the jsp intended to be rendered from the template design-time in the IDE, or runtime on the server?

  • Avoiding Multiple Dialog Calls with htaccess

    - by Jeffrey J Weimer
    OK, I'm new to this, so pardon if the question is already a FAQ. Searching multiple places still leaves me dumbfounded. I have a Web site generated with iWeb09/Mac hosting on an ISP. To secure certain pages, I am trying to set up .htaccess + .htpasswd files. The basic directory structure is ... Main index.html Images.html Images (some css, js stuff) Media Image01 Image01.jpeg ... Image02 Image02.jpeg ... I want to password protect access to the Images directory and all the files therein. The index.html file has a link to the Images.html file that contains the layout for the files in the Images directory. I have put a basic .htaccess file at the Main level that restricts access via ... <Files "Images.html"> AuthType Basic AuthName "Images" AuthUserFile /Main/.htpasswd AuthGroupFile /dev/null Require valid-user </Files> I have then created a valid .htpasswd file. All works at the start, however after the first call to set up the Images.html page, the secure login prompt is displayed multiple times, presumably once for every sub-sub-directory Images/Media/ImageXX (with multiple sub-directories, I just give up after two or three times). I have also tried placing the .htaccess file inside the Images directory with the same problem. Recommendations I have seen suggest a better convention is needed in the basic .htaccess file itself. Alternatively, perhaps a companion .htaccess is needed in the Images directory. So, how do I fix this problem? -- JJW

  • 'Bank Switching' Sprites on old NES applications

    - by Jeffrey Kern
    I'm currently writing in C# what could basically be called my own interpretation of the NES hardware for an old-school looking game that I'm developing. I've fired up FCE and have been observing how the NES displayed and rendered graphics. In a nutshell, the NES could hold two bitmaps worth of graphical information, each with the dimensions of 128x128. These are called the PPU tables. One was for BG tiles and the other was for sprites. The data had to be in this memory for it to be drawn on-screen. Now, if a game had more graphical data then these two banks, it could write portions of this new information to these banks -overwriting what was there - at the end of each frame, and use it from the next frame onward. So, in old games how did the programmers 'bank switch'? I mean, within the level design, how did they know which graphic set to load? I've noticed that Mega Man 2 bankswitches when the screen programatically scrolls from one portion of the stage to the next. But how did they store this information in the level - what sprites to copy over into the PPU tables, and where to write them at? Another example would be hitting pause in MM2. BG tiles get over-written during pause, and then get restored when the player unpauses. How did they remember which tiles they replaced and how to restore them? If I was lazy, I could just make one huge static bitmap and just grab values that way. But I'm forcing myself to limit these values to create a more authentic experience. I've read the amazing guide on how M.C. Kids was made, and I'm trying to be barebones about how I program this game. It still just boggles my mind how these programmers accomplisehd what they did with what they had. EDIT: The only solution I can think of would be to hold separate tables that state what tiles should be in the PPU at what time, but I think that would be a huge memory resource that the NES wouldn't be able to handle.

  • C# WebBrowser Invoke issue

    - by James Jeffrey
    I am logging into facebook using a web browser. Everything works, but the problem is when I invoke the button click I need to check if the password is correct but, the check seems to happen before the button is invoked which makes no sense at all because the checking code is after the invoke. private void Facebook_Login(String username, String password) { webBrowser1.Url = new Uri("http://m.facebook.com"); while (webBrowser1.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); HtmlElementCollection inputs = webBrowser1.Document.GetElementsByTagName("input"); foreach(HtmlElement input in inputs) { if (input.GetAttribute("name") == "email") { input.SetAttribute("value", "[email protected]"); } if (input.GetAttribute("name") == "pass") { input.SetAttribute("value", "kelaroostj"); // dont worry that pass wont work lol. } if (input.GetAttribute("name") == "login") { input.InvokeMember("click"); } } while (webBrowser1.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); HtmlElementCollection bs = webBrowser1.Document.GetElementsByTagName("b"); foreach(HtmlElement b in bs) { MessageBox.Show(b.InnerHtml); } Log_Message("Logged into Facebook with: [email protected]"); }

  • How to Command Query Responsibility Segregation (CQRS) with ASP.NET MVC?

    - by Jeffrey
    I have been reading about Command Query Responsibility Segregation (CQRS). I sort of wonder how would this work with ASP.NET MVC? I get the idea of CQRS conceptually it sounds nice and sure does introduce some complexities (event and messaging pattern) compared to the "normal/common" approach . Also the idea of CQRS sort of against the use of ORM in some ways. I am trying to think how I could use this pattern in the coming projects so if anyone has experience in combining CQRS with ASP.NET MVC and NHibernate please give some concrete examples to help me better understand CQRS and use with ASP.NET MVC. Thanks!

  • Is MapReduce one form of Continuation-Passing Style (CPS)?

    - by Jeffrey
    As the title says. I was reading Yet Another Language Geek: Continuation-Passing Style and I was sort of wondering if MapReduce can be categorized as one form of Continuation-Passing Style aka CPS. I am also wondering how can CPS utilise more than one computer to perform complex computation. Maybe CPS makes it easier to work with Actor model.

  • Creating a Multiwindowed Cocoa Program - Launching Procedure Suggestions?

    - by Jeffrey Kern
    I'm porting an application I developed in Visual Studio 2008 over to Cocoa. I'm currently doing a 'learn-as-you-go' approach to Cocoa, so I can experiment with different ideas and techniques in smaller, simpler projects and eventually combine them into one big application. My program logic is as follows (in a dumbed-down sense). Items in the list are mandated by my boss. Application is started 1a. Verify CD program is in drive. Verify license. If found and is valid, skip to step 7 Display license agreement. Display serial number prompt. Verify and save serial number. Hide all prior windows. Load main application window Intercept requests and commands from main application window, including making a duplicate main application window Exit program when requested by user What would the best bet be for this type of application? From another question I asked, I found out that I should keep the 'main application' window in a separate XIB file from the rest, because I might need to clone and interact with it. I know that since Cocoa and Objective-C is based off of C, there is a Main method somewhere. But what would you all suggest as a starting place for an application like this?

  • Debugging MEF running in ASP.NET

    - by Jeffrey Lott
    I'm trying to do a proof of concept app for my work using ASP.NET WebForms and the Managed Extensibility Framework. I've got things up and running(ish), but I can't seem to figure out how to attach the instance of Visual Studio that has the MEF code in it to the instance of Visual Studio that is running the Web App. How can I attach my MEF code to the running process so that it hits my breakpoints?

  • NES Programming - Nametables?

    - by Jeffrey Kern
    Hello everyone, I'm wondering about how the NES displays its graphical muscle. I've researched stuff online and read through it, but I'm wondering about one last thing: Nametables. Basically, from what I've read, each 8x8 block in a NES nametable points to a location in the pattern table, which holds graphic memory. In addition, the nametable also has an attribute table which sets a certain color palette for each 16x16 block. They're linked up together like this: (assuming 16 8x8 blocks) Nametable, with A B C D = pointers to sprite data: ABBB CDCC DDDD DDDD Attribute table, with 1 2 3 = pointers to color palette data, with < referencing value to the left, ^ above, and ' to the left and above: 1<2< ^'^' 3<3< ^'^' So, in the example above, the blocks would be colored as so 1A 1B 2B 2B 1C 1D 2C 2C 3D 3D 3D 3D 3D 3D 3D 3D Now, if I have this on a fixed screen - it works great! Because the NES resolution is 256x240 pixels. Now, how do these tables get adjusted for scrolling? Because Nametable 0 can scroll into Nametable 1, and if you keep scrolling Nametable 0 will wrap around again. That I get. But what I don't get is how to scroll the attribute table wraps around as well. From what I've read online, the 16x16 blocks it assigns attributes for will cause color distortions on the edge tiles of the screen (as seen when you scroll left to right and vice-versa in SMB3). The concern I have is that I understand how to scroll the nametables, but how do you scroll the attribute table? For intsance, if I have a green block on the left side of the screen, moving the screen to right should in theory cause the tiles to the right to be green as well until they move more into frame, to which they'll revert to their normal colors.

  • 60K+ Sprites on the 360?

    - by Jeffrey Kern
    Hey everyone, Just wondering - throwing ideas in my head - about starting a new XNA project for the 360. I would like it to be retro-old school, and emulating scanlines and color palettes and such. As part of this idea, what I would ideally like to do is manually draw each and every pixel of the screen. So, worst-case scenario I would have to draw about 60K sprites on a 252x240 resolution (I think thats correct). 60K sprites on the screen at a time. So, before I even attempt to code this - would the XBOX 360 be able to keep up with this even? That is a lot of sprites, but they aren't big sprites, and the texture data needed would be non-existant. However, I guess how this project would be implemented would make it or break it, but all I was thinking was coming up with a 2D array and mapping which color value would need to be drawn at that point. Of course, this is watered down talk right now. But what you all suggest? EDIT: Each sprite would represent one pixel. E.g., a sprite at 0,0. Another at 0,1. etc.
